AR1 Automatic Reverse Controller

Digitrax AR1 Automatic Reverse Controller

The Digitrax AR1 is the easy, cost-effective way to add automatic reversing to your DCC layout. It senses polarity mismatches and switches polarity automatically as the train crosses the insulated gaps. No external power supply is required (it runs off track power) and wiring is a simple 4-wire hookup. Fine-tune its tunable trip current to match your booster and rolling stock.
